Sanitary Napkin Raw Materials Overview

Sanitary napkins, also known as menstrual pads, are essential hygiene products used by women worldwide. The quality and comfort of these products largely depend on the raw materials used in their production. Understanding the components of sanitary napkins helps consumers make informed choices and ensures better health and environmental outcomes.

Core Absorbent Materials

The primary function of a sanitary napkin is to absorb menstrual fluid effectively. The core absorbent layer is typically made from:

• Wood Pulp: The most common absorbent material, providing excellent liquid retention.
• Super Absorbent Polymer (SAP): A synthetic material that can absorb many times its weight in liquid.
• Cotton: Used in premium products for its softness and breathability.

Top Sheet Materials

The top sheet is the layer that comes in direct contact with the skin. Key materials include:

• Non-woven Fabric: A porous material that allows quick liquid penetration while keeping the surface dry.
• Perforated Film: Used in some products for enhanced dryness.
• Organic Cotton: Preferred by eco-conscious consumers for its natural properties.

Back Sheet Materials

The back sheet prevents leakage and keeps moisture from reaching clothing. Common options are:

• Polyethylene (PE) Film: The most widely used waterproof backing material.
• Biodegradable Films: Environmentally friendly alternatives made from plant-based materials.
• Breathable Microporous Films: Allow air circulation while maintaining protection.

Adhesive Components

To keep the napkin securely in place, manufacturers use:

• Pressure-sensitive Adhesives: Applied to the back sheet for panty attachment.
• Wing Adhesives: Used in winged napkins for extra security.

Additional Components

Modern sanitary napkins may also include:

• Fragrance: Added to some products for odor control (though may cause irritation for some users).
• Antibacterial Agents: Sometimes incorporated to prevent bacterial growth.
• Colorants: Used for aesthetic purposes in some brands.

Environmental Considerations

With growing environmental awareness, manufacturers are increasingly using:

• Bamboo Fiber: A sustainable alternative to wood pulp.
• Biodegradable SAP: New formulations that break down more easily.
• Plant-based Plastics: For back sheets and packaging.

Understanding these materials helps consumers choose products that align with their comfort needs, health requirements, and environmental values. As technology advances, we can expect to see more innovative and sustainable materials entering the sanitary napkin market.
